Intel 2.21.9 X.Org Driver Calls Out More Regressions

Chris Wilson of Intel's Open-Source Technology Center is back to pushing out xf86-video-intel driver updates at an expedited rate. Rather than the new releases being about advancing the SNA acceleration architecture or new features, the past few have been about correcting regressions and other bugs.

Just one week after the last xf86-video-intel DDX update, Chris released the xf86-video-intel 2.21.9 driver this morning. "Consolidating the copy-on-write support, hopefully cleaning up the last of the regressions."

This new Intel X.Org driver release hopefully restores v-sync on textured videos, fixes a performance regression from not promoting large fills to the GPU, undoing a pixmap clone before doing a DRI2 copy region call, and fixing the ordering of possible clones. A performance regression found within my recent SNA vs. UXA benchmarks has also been taken care of.
